6. TYPES OF RADIATION
1) Ionizing radiations.
2) Non ionizing radiations.
1. IONIZING RADIATION :-
Higher energy electromagnetic
waves (gamma) or heavy particles (beta
and alpha).

8. High enough energy to pull electron from
orbit.
 E.G :-
Alpha particles.
Beta particles.
Gamma rays.
2. NON IONIZING RADIATIONS :-
Longer wavelength and low energy.
Not enough energy to pull electron from
orbit.
Lower energy electro magenetic waves.

9. E.G:-
oUltraviolet radiations (UV).
o Visible light.
oInfrared radiation.
o Microwave radiation.
o Radio frequency radiation.

11. EFFECTS OF RADIATION ON PLANT
GROWTH & DEVELOPMENT
Prevents seed growth ultraviolet
radiation effects plant growth and
development in many ways.
First it gradually stops seed growth and
depended on the how much radiation is
released.

12. The stomata is a small air hole with in a
plant leaf that also controls water levels.
If the stomata is unable to open for a long
period of time ,the growth of the plant.
Damages plant cells.
The cells of living organism are also
damaged and killed by ultraviolet radiation.
Cells contain responsible for plant
reproduction.if the needed for
photosynthesis and normal plant growth.

13. DAMAGES PLANT CELLS
 The cells of living organism are also
damaged and killed by ultraviolet radiation.
 What allows plants to grow is the division
and expansion of cells as they take up
water.
 Cells contain chromosomes, the genetic
material responsible for plant reproduction.
 If the cell is overly damaged by radiation,
then reproduction is hindered.
